Research and Design of Nodes for Field Observation Instruments Networking

摘要

—The harsh natural environment of cold and arid regions results in difficult to obtain information and severely restricts the development of Geoscience. To build up networks of field observation instruments in cold and arid regions, and promote the overall automation and realtime of field observation data transfer, the instrument networking node and gateway node were designed in this paper. The designed nodes have the properties of smaller size, lower power consumption, and could accomplish the tasks of data collection and transmission, and construct observation instruments networking in cold and arid regions. To achieve the standardization control of data acquisition device, a standardized, integrated, and transparent commands set was proposed for data loggers which can reduce the complexity of software development and improve system's universality and portability.
